TheProfile Z Coaster Rear BMX Hubis a proprietary freecoaster style hub engineered, designed, & manufactured by Profile Racing. It essentially works as a spring/pawl cassette hub that can be disengaged into a freecoaster with varying slack options.

Features

• The Z Coasters Pawl is Z shaped to allow for engagement/disengagement by the center Slack Cam Ring. This allows for adjustable slack by being able to switch cam rings. They are available in 20/33/45 deg, 60 deg, 75 deg, 90 deg, & 115 deg slack opti0ns. This means you can dial in the slack from less than 1/8 of a crank to a full 1/3 of a crank!
